Components of Model-View-Controller (MVC) Architecture in Struts

Struts follows the Model-View-Controller (MVC) architecture pattern to facilitate web development. The different components of MVC in Struts are:

1. Model:

The Model represents the data and business logic of the application. It is responsible for managing the application's data, processing user inputs, and interacting with the database. In Struts, the Model is typically implemented using JavaBeans or other POJO classes.

2. View:

The View is responsible for rendering the user interface of the application. It presents the data to the user in a user-friendly manner. In Struts, the View is usually implemented using JSP (JavaServer Pages) or other templating technologies.

3. Controller:

The Controller acts as an intermediary between the Model and the View. It is responsible for processing user requests, invoking the appropriate business logic in the Model, and selecting the appropriate View to render the response. In Struts, the Controller is typically implemented using the ActionServlet and Action classes.

Interaction between Components:

In Struts, the interaction between the Model, View, and Controller is as follows:

• 1. When a user sends a request to the application, it is first received by the Controller (ActionServlet).
• 2. The Controller processes the request, invokes the appropriate business logic in the Model, and prepares the data to be displayed.
• 3. The Controller then selects the appropriate View (JSP) to render the response based on the outcome of the request processing.
• 4. The View receives the data from the Controller and generates the HTML output to be sent back to the user.
• 5. The final HTML response is then sent back to the user's browser for display.

Overall, the MVC architecture in Struts separates the concerns of data management, user interface presentation, and application flow, making it easier to maintain and extend web applications.
